尝试安装Python for Windows扩展时出现值错误

问题描述

我已安装Microsoft Visual Studio 2008。我下载了zip文件，提取内容到我的Python27文件夹。现在有一个名为pywin32-214的子文件夹。 （这是32部分是一个问题？我在一个64位系统上。）这是命令行的一个脚本：

I have Microsoft Visual Studio 2008 installed already. I downloaded the zip file Python for Windows extensions and extracted the contents into my Python27 folder. There's now a subfolder called pywin32-214. (Is the 32 part a problem? I'm on a 64-bit system.) Here's a transcript from the command line:

C:\Python27\pywin32-214>setup.py -q install

我不知道该怎么做。帮助？

I don't know what to make of this. Help?

推荐答案

如果您有64位Python安装：

If you have a 64 bit Python installation:

安装Microsoft Visual Studio 2008 Professional Edition并启用X64编译器和工具选项。

Install "Microsoft Visual Studio 2008 Professional Edition" with the "X64 Compiler and Tools" option enabled.

或者，下载pywin32-214.win-amd64-py2.7 .exe从

Alternatively, download pywin32-214.win-amd64-py2.7.exe from http://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/
